Definitions
- This invention relates to metering valves and in particular to deflectible beam-type metering valves.
- a fine metering valve having a deflectible beam and means for deflecting the beam adjustably adjacent a valve port for metering the fluid flow through the valve.
- Deflection of the beam is effected in the Hiszpanski patent by a displacement reduction means which includes a spring extending between a threaded member and a seat engaging the beam. As the spring is resiliently compressible, a threaded advance of the threaded member provides a reduced displacement for fine control of the deflection of the beam.
- the present invention comprehends a metering valve construction comprising a further improvement over that of the above described Hiszpanski metering valve.
- One improved feature of the present metering valve is the provision therein of a removable orifice disc aligned with the inlet to define the inlet port underlying the deflectible beam.
- the orifice disc may be any one of a plurality of orifice discs having different size orifices.
- the invention comprehends the utilization of the same deflectible beam with any one of the selected orifice discs, as desired.
- the orifice disc may be retained in the valve by a clamping of a peripheral portion thereof between separable portions of the wall means of the valve.
- the separable wall portions comprise the valve body and bonnet portions of the valve. More specifically, in the illustrated embodiment, the peripheral portion of the orifice disc is clamped between the inner end of the bonnet and an inner surface of the valve body defining a portion of the inner valve chamber.
- the invention further comprehends the arrangement of the outlet to extend around the periphery of the orifice disc for effectively minimizing the axial extent of the valve.
- the outlet may include a duct portion extending through the bonnet adjacent the beam to an annular space defined cooperatively by the body, bonnet, and peripheral portion of the orifice disc.
- the annular space may open to a duct portion through the valve body opening to exteriorly of the valve.
- the deflectible beam may be carried on a suitable spacer ring supported on the orifice disc.
- the force applying means for effecting the desired deflection of the beam may include a threaded stem adjustably threaded to the bonnet for selective movement of an inner end surface thereof toward and from the deflectible beam. Force is transferred from the threaded stem to the deflectible beam by a displacement reduction means including a coil spring.
- a first spring retainer receives one end of the spring adjacent the deflectible beam and defines a frustoconical surface, the tip of which engages the beam under the biasing action of the spring.
- the outer periphery of the spring retainer may be cylindrical for accurate sliding engagement in a cylindrical portion of the bonnet outwardly of the outlet port.
- the other end of the spring is provided with a second spring retainer.
- the second spring retainer may comprise a mushroom element having a conical outer surface on the head portion thereof arranged to have point contact with the threaded stem so as to effectively minimize rotational force transmission between the threaded stem and the second spring retainer.
- the second spring retainer may further include a stem portion received in the outer end of the spring. Resultingly, threaded movement of the stem in the bonnet effects selectively a contraction or expansion of the coil spring between the opposite spring retainers to effect the desired displacement reduction deflection of the beam.
- the metering valve of the present invention is extremely simple and economical of construction while yet providing the highly desirable advantages discussed above.
- FIG. 1 is a vertical section of a metering valve embodying the invention
- FIG. 2 is a transverse section thereof taken substantially along the line 2--2 of FIG. 1;
- FIG. 3 is a fragmentary vertical section illustrating the arrangement of the valve with the beam in a deflected position.
- a metering valve generally designated 10 is shown to comprise a body generally designated 11 and a bonnet generally designated 12.
- the bonnet is removably threaded to the body by means of a threaded lower portion 13 on the bonnet, and a threaded recess 14 in the body.
- a suitable O-ring 15 may be provided for sealing the bonnet to the body in assembled relationship.
- Body 11 further defines an inlet duct 16 and an outlet duct 17.
- the body and bonnet cooperatively define an inner flow chamber 18 providing communication between the inlet 16 and the outlet 17.
- a deflectible beam 19 which is juxtaposed to the inlet 16 within the flow chamber 18, as shown in FIG. 1.
- the beam is supported on an annular support 20 which illustratively may comprise a spacer ring, and which, in turn, is carried on an orifice disc 21.
- the orifice disc is provided with an axial port 22 which effectively defines an inlet port to flow chamber 18 in the assembled arrangement of the valve as shown in FIG. 1.
- Orifice disc 21 further defines a peripheral portion 23 which is sealingly clamped between a flat surface 24 of body 11 defining a portion of the wall of flow chamber 18, and the lower end 25 of the bonnet which may be provided with a suitable annular recess 26 for receiving the disc peripheral portion 23 and thereby centering port 22 in axial alignment with inlet duct 16 of the body.
- Bonnet 12 further defines a pair of ducts 27 opening to an outer annular recess 28, in turn communicating with body outlet duct 17, as best seen in FIG. 2.
- the peripheral portion 23 of orifice disc 21 cooperates with the lower end 25 of the bonnet and the portion of body 11 surrounding the inner end of outlet duct 17 to define the annular space 28 for conducting fluid from the bonnet outlet ducts 27 to the body outlet duct 17.
- the upper end of the bonnet may be closed by a suitable cap 29 having an internally threaded portion 30 threadedly mounted to an externally threaded portion 31 of the bonnet.
- Extending through the cap is the stem portion 32 of a force member generally designated 33 having a lower threaded portion 34 threaded into a threaded recess 35 in the upper portion of the bonnet.
- the stem 32 is rotatably sealed to the bonnet by means of an O-ring 36 and washer 37 mounted about the stem above the threaded portion 34.
- An operating knob 38 is secured to the distal end 39 of the stem portion 32 by a suitable set screw 40.
- a displacement reduction means generally designated 41 is interposed between the lower surface 42 of stem portion 34 and beam 19.
- the displacement reduction means functions to deflect the beam a small amount for a given amount of axial movement of the force member 33, and for this purpose, includes a coil spring 43, a first spring seat retainer 44, and a second spring seat retainer 45.
- spring seat retainer 44 is defined by a lower frustoconical surface 46 having a lower end 47 engaging the midportion of beam 19.
- Retainer 44 further defines a cylindrical sidewall 48 slidably received in a cylindrical bore portion 49 of bonnet 12 opening to chamber 18.
- the lower end 50 of spring 43 is received in a cylindrical recess 51 of the retainer 44 opening oppositely to end, or tip, 47.
- the upper, second spring seat retainer 45 comprises a mushroom element having head portion 52 and a stem portion 53.
- Head portion 52 defines an upper conical surface 54 having a tip 55.
- Stem portion 53 is received within the upper end 56 of the spring 43.
- the orifice disc 21 comprises any one of a plurality of different such discs having different diameter ports 22.
- the selected orifice disc may be installed readily in the valve upon removal of bonnet 12 from the body.
- the orifice disc 21, spacer ring 20, beam 19, and displacement reduction means 41 may be installed in the lower end of the bonnet with the force member 33 retracted so that upon reinstallation of the bonnet 12 with these elements so assembled therein, the valve may be readily restored to the assembled relationship of FIG. 1.
- the same beam 19 may be utilized with a wide range of port sizes of the different orifice discs whereby facilitated selective use of the metering valve over a substantial range of desired flow control conditions may be readily obtained.
